hello, i was in need to send email to serveur on port 25 using NO tls/ssl BUT using 3DES algorythm. i'm neewbe in encryption, but founded samples with 3DES email encryption with 3DES. http://www.example-code.com/vcpp/Send3DESMail.asp BUT, the question, is..
WHERE OR HOW TO GET THIS CERT for 3DES encryption.?
the computer who will send email don't have Outlook or other thing to get cert or use Embedded database cert.. are they any way to get it from email sent from the receiver.?? or other way.?
The certificate is something you receive externally from the person you would be sending email to. The example you reference is old, and a newer/correct example is at http://www.example-code.com/cpp/Send3DESMail.asp (notice the "/cpp/" in the URL vs. "/vcpp/")
